Used DT 240s or new Hope Pro 2?

I have a set of 26" EX1750s with 240s hubs that I was thinking of building up with Flow 29ers. The hubs look and feel new. If I do this, the 36 tooth upgrade will be made. OR should I build up a set of HOPE Pro 2s with flows? I only have about $400 in the DT wheelset but the Aerolite spokes and 5.1 rims are in good shape...

Either way you cannot go wrong. Other than you will only have one wheel set to play with if you build up the dt's. Personally I'm all about trying new things. And the hopes would be new and different...but much louder.
